In the lovelace UI, you can overwrite the friendly name of an entity in the entity or glance card. This is impossible for badges. The feature request is, to also add this for badges, so something like this will work:
title: Default view badges: - entity: sun.sun name: SSUUNN cards: ...
Entity names:
With this feature, a long sensor name can be shortened for a specific badge only.
Isn’t the doc proposing it? Not tried, but presented as possible (see ‘options for badges’):
You are right. I tested this. I am fairly sure this didn’t work until some time ago. It has probably been implemented silently. Nice!
Is using the raw config editor the only way to add this? It does not appear to be part of the GUI yet.
